As giant lizards once roamed our planet, so did mammoth machines once balance our checkbooks. We’ve dedicated this photo gallery to the outdated computer hardware that fills museums, supply closets, storage lockers, and techie basements everywhere. Find out just how far back your computer experience goes as you browse photos of computers from ENIAC to RadioShack’s TRS-80.

Share your dinosaur sightings!

Send us photos of your favorite old computer equipment and we may add them to the gallery. Be sure to describe the equipment and share your favorite memories of working with it.
